Gravisensitivity in new moss species was determined and some peculiarities of their gravimorphoses on different stages of the ontogenesis were analyzed. It was established that gravireactions promote the formation of new phenotype and increase in phenotypic plasticity of the gametophytic and sporophytic stages of bryophytes ontogenesis. It was shown for the first time that gravity facilitates vegetative reproduction activity and plays an important role in the realization of reproductive strategy of mosses
